Description
Technical Field
The utility model relates to an electrode plate structure for a high-voltage electrolytic tank, an electrolytic unit structure formed by the electrode plate and a high-voltage electrolytic tank formed by the electrolytic unit structure, and belongs to the technical field of pressure electrolytic tanks.
Background
Chinese patent publication No. CN219032404U discloses an electrolyzer for producing high pressure hydrogen and oxygen, as shown in fig. 1. The electrolytic cell comprises three regular polygon planar pieces, namely a polar plate, a sealing gasket and a diaphragm, wherein the polar plate, the sealing gasket and the diaphragm are in planar contact, and each electrolytic cell group is formed by overlapping and closely contacting a first sealing gasket 103, an anode plate 104, the first sealing gasket 103, a diaphragm 105, a second sealing gasket 106, a cathode plate 107, a second sealing gasket 106 and the diaphragm 105. Since the plates, gaskets and diaphragms of the electrolysis cell stack all lie flat against each other, a flat seal is formed between the compressed plates, gaskets and diaphragms. However, in the subsequent experiments for manufacturing the electrolytic cell, the inventors of the above patent found that when the electrolytic cell gradually forms high pressure as the electrolytic reaction continuously generates gases (hydrogen and oxygen), gas-liquid leakage occurs between the polar plate, the sealing gasket and the diaphragm, that is, the sealing becomes ineffective. For this reason, the inventors of the above-mentioned patent have intensively studied the assembly sealing structure of the electrolytic cell group and made further improvements thereto.
Disclosure of Invention
The utility model aims to solve the technical problems that: the above patent discloses an electrode plate of an electrolytic cell and its constituent structure are improved to meet the requirement of high-pressure electrolytic sealing, and an electrolytic cell with reliable sealing are formed to realize high-pressure hydrogen and oxygen production.
The first technical scheme provided by the utility model for solving the technical problems is as follows: the electrolytic unit with the sealing gasket comprises a pair of electrode plates, the sealing gasket which is attached to the front side surface and the back side surface of the electrode plates, and an electrolytic diaphragm which is clamped between the opposite side surfaces of the pair of electrode plates, wherein one electrode plate is connected with a positive electrode of a power supply and the other electrode plate is connected with a negative electrode of the power supply; the outer side surfaces of the sealing gaskets are provided with convex rings, and the diameters of the two convex rings of the two sealing gaskets on the two opposite side surfaces of the pair of electrode plates are different; the convex ring of the sealing gasket on one electrode plate of the pair of electrode plates is abutted against one side surface of the electrolytic diaphragm to form a first coil wire seal, and the convex ring of the sealing gasket on the other electrode plate is abutted against the other side surface of the electrolytic diaphragm to form a second coil wire seal; the first coil seal and the second coil seal are staggered from each other on the circumference; the sealing gasket forms radial limit relative to the electrode plate.
The second technical scheme provided by the utility model for solving the technical problems is as follows: the high-voltage electrolytic tank is formed by stacking and pressing a plurality of electrolytic units in the second technical scheme, the liquid inlet holes and the corresponding film openings are used for allowing electrolyte to enter and fill the electrolytic areas on the front side and the back side of the electrode plate, and the two liquid outlet holes and the corresponding film openings are used for respectively leading out gas and liquid after the electrolytic reaction on the cathode side and the anode side.
The inventor of the present patent application studied intensively the above-mentioned assembly sealing structure of the existing electrolytic cell group: 1. the flat seal is formed among the pole plate, the sealing gasket and the diaphragm after the compression, the flatness of the sealing surfaces of the pole plate, the sealing gasket and the diaphragm is difficult to achieve high precision due to the processing precision, when the gas-liquid is gradually generated in the electrolytic reaction area to form high pressure, a large pressure difference is formed between the gas-liquid and the outside, and under the action of the large pressure difference, the sealing failure among the pole plate, the sealing gasket and the diaphragm is easy to be caused; 2. because the plane seal is formed among the polar plate, the sealing gasket and the diaphragm, the axial stress is applied to form constraint after the compression, but the constraint is not effective in the radial direction, the polar plate, the sealing gasket and the diaphragm are easy to generate tiny movement on the plane under the action force of high-pressure gas and liquid generated in an electrolytic reaction area, and the sealing among the polar plate, the sealing gasket and the diaphragm is easy to lose efficacy.
The beneficial effects of the utility model are as follows: because the sealing gaskets are designed and filled between the side surfaces of the pair of electrode plates, when the pair of electrode plates forming the cathode electrode and the anode electrode are oppositely attached and the electrolytic membrane is clamped between the pair of electrode plates, the two sealing gaskets on the opposite side surfaces of the pair of electrode plates are respectively staggered with the two side surfaces of the electrolytic membrane (the first coil of wire sealing and the second coil of wire sealing), the plane sealing between the conventional sealing gaskets and the electrolytic membrane and the electrode plates is changed into the two coil of wire sealing, the sealing performance is greatly improved, and the pressure difference between an electrolytic reaction area and the outside is greatly resisted without leakage. As for the pressure difference between the corresponding liquid inlet hole of the inner ring of the electrolytic diaphragm and the membrane opening hole of the liquid outlet hole, the sealing of the outer ring of the electrolytic diaphragm is ensured, so that the gas-liquid pressure difference of the inner ring of the electrolytic diaphragm gradually balances itself and disappears. When the high-pressure electrolytic tank is formed by the electrolytic unit, the high-pressure electrolytic tank and the electrolytic unit thereof can reach the required high pressure after continuous electrolysis without worrying about leakage, thereby realizing the high-pressure hydrogen-to-oxygen production without leakage, namely producing high-pressure hydrogen and oxygen.
Further, annular grooves are formed in the peripheral edges of the electrolytic area on the front side surface and the back side surface of the electrode plate, and all or part of the sealing gasket is filled into the annular grooves to form radial limit between the sealing gasket and the side surface of the electrode plate.
Further, the surface of the sealing gasket, which is in contact with the electrode plate, is provided with grains, and when friction force is formed on the surface of the sealing gasket, which is in contact with the electrode plate, radial limit is formed between the sealing gasket and the side surface of the electrode plate.
Further, the surfaces of the sealing gasket, which are in contact with the electrode plates, are respectively provided with a protrusion and a groove which are nested with each other, so that radial limit is formed between the sealing gasket and the side surfaces of the electrode plates.
Further, a baffle is arranged on the outer peripheral side of the sealing gasket, and the baffle and the electrode plate form fixed connection so as to form radial limit between the sealing gasket and the side surface of the electrode plate.
Through the improvement and variation, the sealing gasket can be limited to slide outwards in the radial direction, so that the leakage of the inner ring sealing gasket on the side surface of the electrode plate due to radial movement is avoided.
Further, the fixed coupling is a bolt coupling, a weld, a key-to-keyway coupling, or a pin-to-pinhole coupling.
Further, the bead is an O-ring or other shape in cross-section.
Further, the bead is an adhesive strip adhered to the outward-facing hollow side of the gasket.
Further, the bead is a coating formed on the hollow side of the gasket facing outward.
